[0026] Furthermore, the length of the cross bar 2 is 500 mm, and the cross bar 2 is fixed to the U-shaped support bar 1 by welding.
[0027] Furthermore, the U-shaped support rod 1 is a seamless steel pipe that is bent into three sections and formed as one piece. The top of the U-shaped support rod 1 is a straight section, and both ends of the straight section are inclined sections. The bending angle between the straight section and the inclined section is 110°.
[0028] Furthermore, in order to increase the strength of the ladder, the U-shaped support rod 1 and the cross bar 2 are both seamless steel pipes.
[0029] Furthermore, in order to improve the anti-slip effect, a plurality of protrusions are arranged in an array at the bottom of the fixing plate 3 .
[0030] Furthermore, in order to improve the stability of the ladder, the fixing plate 3 is a counterweight steel plate.
[0031] The utility model provides a ladder for inspecting a split-type transformer, and its working principle is as follows: when in use, the fixing plates 3 are placed on both sides of the main oil pipe of the transformer, that is, the ladder straddles the top of the main oil pipe, and the staff climbs the ladder and straddles the main oil pipe by stepping on the cross bar 2 while holding the U-shaped support rod 1 with both hands to observe the operation of the transformer.
[0032] Embodiment 2
[0033] Reference Figure 3-Figure 5The difference between this embodiment and the first embodiment is that a fixed shaft 7 is fixedly connected to one end of the U-shaped support rod 1 close to the fixed plate 3, a guide plate 4 is arranged on the fixed shaft 7, a long waist hole is opened on the guide plate 4, and the guide plate 4 is slidably connected to the U-shaped support rod 1 through the fixed shaft 7 and the long waist hole, and a plum handle bolt 8 is threadedly connected to one end of the U-shaped support rod 1 away from the fixed plate 3, a notch 6 is opened at one end of the guide plate 4, and the notch 6 is connected to the long waist hole, and the guide plate 4 is fixedly connected to the U-shaped support rod 1 through the notch 6 and the plum handle bolt 8, a pull rod 5 is fixedly connected to the guide plate 4, and the guide plate 4 is arranged parallel to the pull rod 5, a fixed tube 9 is hinged on the U-shaped support rod 1, and the fixed tube 9 is arranged opposite to the fixed shaft 7, and a plum handle bolt 2 10 is threadedly connected to the fixed tube 9, and the pull rod 5 is fixedly connected to the U-shaped support rod 1 through the fixed tube 9 and the plum handle bolt 2 10.
